What is the function of magnesium in plants?

Magnesium plays a crucial role in the process of photosynthesis, which is how plants convert light energy into chemical energy. Specifically, magnesium is an essential component of chlorophyll, the green pigment found in plants that is vital for capturing light energy during photosynthesis. Without sufficient magnesium, plants may exhibit poor chlorophyll production, leading to reduced photosynthetic efficiency and potential stunting of growth.

In the context of plant nutrition, magnesium aids in other functions as well, but its primary and most important role is directly tied to photosynthesis, making it critical for healthy plant growth and development.
